WebbBecause the pH scale is logarithmic, there is a 10-fold difference between each unit. For example, pH 5 is 10 times as acid as pH 6 and pH 4 is 100 times as acid as pH 6. The general mathematical formula defining pH is: pH = -log [H+], in which pH is the negative logarithm of the hydrogen ion concentration. Webb• The definition of pH is pH is equal to the negative log (logarithm) of the _____ ion concentration of a solution. • The logarithm of a number is the power to which 10 must …

What is the negative logarithm of hydrogen ion concentration …
WebbThe pH is defined as the negative log 10 of the hydrogen ion concentration expressed in mol/L. A negative logarithmic scale is used because the numbers are all less than 1, and vary over a wide range. … High pH numbers, e.g. pH 7.8, represent lower hydrogen ion concentrations, i.e. alkaline solutions. Is pH a positive or negative logarithm? Webb9 aug. 2024 · The pOHof a solution is the negative logarithm of the hydroxide-ion concentration: \[\text{pOH} = -\text{log} \left[ \ce{OH^-} \right]\nonumber \] The pH of a solution can be related to the pOH. Consider a solution with a pH \(= 4.0\). The \(\left[ \ce{H^+} \right]\) of the solution would be \(1.0 \times 10^{-4} \: \text{M}\).
